Pulsed-wire anemometer measurements have been made in the vicinity of rectangular shaped model buildings immersed in the simulated atmospheric boundary layer of a wind tunnel. The primary purpose of the measurements was to delineate the size and shape of the 'cavity' as a function of the building dimensions. The crosswind width, the height and the along-wind length of the building were systematically varied, and the longitudinal and vertical components of the velocity fields were measured in the plane of symmetry (centerplane). For one case, all three velocity components were measured in the full three-dimensional space surrounding the building. These measurements were used to deduce the streamline patterns and, hence, the height and downwind extent of the recirculation zones or cavities and other important features of the flow fields.
